Definitions

  • the present invention relates to a device for use in removing a windscreen or other glass panel in motor vehicles, said windscreen or glass panel being secured in the vehicle by an elastomeric sealing strip, said device comprising an elongated flexible blade having a sharpened edge at one end and means at the other end to allow the blade to be manually gripped or operably gripped by a reciprocating power tool.
  • windscreens have been fitted to motor vehicles using an elastomeric strip adhesively bonded to an edge region of the glass windscreen and to part of the body work of the vehicle with the elastomeric strip being compressed between the windscreen and the vehicle body work. It is often necessary to remove such windscreens after they have been secured by this method. Typically, once a windscreen has been broken the remaining parts of the windscreen have to be completely removed to allow a new windscreen to be inserted. Other situations occur, for example, when a windscreen requires resealing and needs to be removed for this purpose or when a vehicle owner wishes to replace a shatter windscreen with a laminated windscreen. In these situations, it is desirable to remove the old windscreen without damage so that it can be reused.
  • US Pat. No. 1,521,265 shows a driving tool which at first sight could, in some embodiments, look like a device for removing windscreens, but which actually is not such a device, and which is rather designed for driving out wrist pins, bushings and the like.
  • the objective of the present invention is to provide a device for use in removing stick-in windscreens of the aforementioned type in a manner which minimizes the changes of breakages while decreasing the time taken for the operation.
  • a device for removing from a vehicle a glass panel secured in the vehicle by an elastomeric sealing strip comprising an elongated flexible blade having a sharpened edge at one end and means at the other end to allow the blade to be manually gripped or operably gripped by a reciprocating power tool, characterized in that said sharpened edge extends along a short length of at least one longitudinal edge of said blade from said one end, said sharpened edge being located in the plane of one face of the flexible blade.
  • the blade consists of a generally rectangular strip of flat spring steel, the sharpened end of said blade having a generally semicircular or curved configuration such that substantially no sharp edges are formed when seen in plan view.
  • the blade is preferably sharpened along at least the complete edge formed by said curved configuration region, the sharpening being effected such that the sharpened edge is located in the plane of one of the faces of the blade.
  • the sharpened end of the blade is forced into the region of the elastomeric strip adjacent the windscreen, preferably into the adhesive material forming the bond between the windscreen glass and the elastomeric strip such that the substantially flat face of the blade is engaged against the inner surface of the glass.
  • the blade is preferably inserted such that its axis forms an acute angle with elastomeric strip and thereafter the blade is reciprocated as well as being rocked forward and rearwardly in the direction of the elastomeric strip with the blade moving along the plane of the glass to separate the elastomeric strip from the glass.
  • the elastomeric strip includes an edge strip peripherally surrounding the windscreen, the blade may then be inserted from the outside along the edge strip to allow removal of the windscreen from the vehicle body. In this operation it is preferable to use a blade of shorter length as great flexibility is not needed due to the fact that there are no substantial obstacles on the external side of the windscreen.
  • the holder 2 may be of metal construction or alternatively of moulded plastics material.
  • the holder 2 includes a socket 6 adapted to receive an end 9 of the blade 1.
  • a screw 7 releasably secures the blade 1 within the socket 6. It will, however, be appreciated that other means for securing the blade to the holder may be employed or alternatively, the holder may be permanently secured to the blade.
  • the holder 2 includes a collar and hammer stem 8 adapted to fit in a pneumatically operated reciprocable tool such as a pneumatic chisel.
  • a manual handle 15 shown in phantom outline may be provided with a bore of a dimension such that it fits over the hammer stem 8 with a friction fit thereon.
  • the end 9 of the blade 1 may include a non slip grip covering for use when the blade device is being used manually.
  • the blade 1 has a sharpened end 3 of a generally semicircular configuration when seen in plan view. In consequence, in the plan view there are no sharp edges or corners which could engage or damage the vehicle body or windscreen during a removal operation.
  • the semicircular sharpened end 3 initially has its forward end ground tapering towards the most forward extremity of the blade. Furthermore, the longitudinal side edges of the blade are ground tapering towards the side edges for a short distance along the blade. The length of this region need only be of sufficient dimension to ensure that when the blade is inserted in the elastomeric sealing strip, a sharpened region of the blade is always in contact with the strip.
  • FIGS 1C and 1D show the blade of Figures 1 A and 1 B subsequently sharpened by a user of the device using a sharpening stone or the like.
  • the sharpened end produced has a very sharp edge 4 with a curved face 17 of the blade.
  • Figures 1 E and 1 F demonstrate an alternative embodiment wherein the sharp edge 4 is formed by a curved surface 5 peripherally surrounding the end 3 of the blade. Again the end 3 is semicircular in plan view and the sharpened edge 4 is in the face 16 of the blade and extends a short distance along the blade itself.
  • FIGs 2, 3 and 4 of the drawings show how the device is used to remove a vehicle windscreen.
  • a windscreen 10 adhesively bonded to an elastomeric edge strip 11, the strip 11 being bonded to a vehicle frame part 12.
  • An outer metal edge strip 13 covers the edge region of the windscreen.
  • the blade 1 of the device according to the present invention is either operated manually or secured within a reciprocating power tool 18.
  • the blade 1 is transversely flexible and is guided at an acute angle to the strip 11 to reciprocate along the plane of the glass windscreen with the sharp edge 4 of the blade travelling along the plane of the glass.
  • the blade is worked into and through the strip 11 to break or cut the bond between the glass and strip.
  • FIG 3 is a view similar of Figure 2 wherein the strip 11 includes an edge region 19 peripherally surrounding the windscreen.
  • the blade 1 is operated firstly within the vehicle as with Figure 2 and then the edge region 19 is cut in a similar manner from the outside of the vehicle.
  • the outer cut may be achieved using a blade of substantially shorter length than that required for the more difficult cut on the inner side of the windscreen. Furthermore there are no obstacles on the outer side and thus substantial flexibility is not of any great advantage.
  • the blade 1 may be given a permanently curved longitudinal axis.
  • a curved blade of this configuration is of particular advantage when the blade length is short, thereby minimizing the effort required to flex the blade for use.
  • the present invention provides an apparatus for removing windscreens from vehicles in a relatively quick manner without any great difficulty or complication and without any unnecessary breakage of the windscreen. As a result, danger from splintered or fractured glass is avoided and damage to the vehicle is minimized. In addition, the elastomeric sealing strip is largely left in one piece which makes it far easier and simpler to remove.
